What Latitude actually costs

There is no published total. The two knowable pieces: in-network diagnostics and visits (your deductible and copays across 6–12 months of frequent appointments), plus a one-time OIT program fee that Latitude's FAQ calls a non-covered service. Patients report that fee at "over $4,000" in the Bay Area and "over $5,000" in New York — treat that as a range that may vary by region, allergen count, and time. After active treatment comes lifelong maintenance dosing and long-term care, whose cost is also unpublished. For context, in-person food allergy programs can cost $10,000+ per year.

The clinic does not say. Unpublished pricing is common where insurance covers part of the picture and case complexity varies — a single-allergen toddler and a multi-allergen adult are genuinely different programs. The practical consequence for families is that the number arrives in a consultation rather than on a web page, so the questions listed on this page belong in that consultation, in writing. One Bay Area patient's reaction on Reddit — "this is shocking given I did plenty of research" — is exactly the surprise a written pre-estimate prevents.

Partially, per its own FAQ. Diagnostics and visits are "typically covered" in-network, and the insurer lists are regional: Aetna, Anthem Blue Cross, Blue Shield, Cigna, Health Net, UnitedHealthcare, and select HMOs in Northern California; Aetna, Anthem, Empire BlueCross, Cigna, Oxford, and UHC in New York; Aetna, Blue Cross, Blue Shield, Cigna, HealthNet, and UHC in Southern California. The one-time OIT program fee is explicitly not covered by any of them. It is FSA/HSA eligible and payment plans exist, which softens the cash-flow hit without changing the total.

The program fee — the non-covered part — at "over $4,000" from a Bay Area patient on Reddit and "over $5,000" from a New York reviewer on Atly, who called it "cost prohibitive." The figures conflict slightly, plausibly by region or over time, so honest reporting shows them as a range: $4,000–$5,000+. On top of the fee sits whatever your plan leaves you of in-network visits and diagnostics across the 6–12 month active phase, then maintenance. Notably, there is no cluster of billing-dispute complaints in Latitude's public record; its BBB profile is Not Rated with no complaints on file.

FAI publishes its subscription: $979/month for ages 18–25 and $1,079/month for ages 26–50 with a 6-month minimum, and its own cost page estimates the first year at roughly $11,748 on the cash path or $15,425 on the insurance path, over a typical 2.5–4 year program. Latitude's patient-reported $4,000–$5,000+ fee plus in-network visits over 6–12 months of active treatment is a smaller headline number over a much shorter active phase — but it is unpublished, so it needs confirming per case. The full three-way comparison, including Curex, is at [food allergy clinics compared](/learn/food-allergy-clinics-compared), and FAI's numbers get the same treatment at [Food Allergy Institute cost](/learn/food-allergy-institute-cost).

Latitude publishes strong figures: 94% of patients of all ages and 98% of patients under 4 achieved desensitization with oral immunotherapy (source: internal data, 2026), and an AAAAI 2025 abstract with Weill Cornell reported that about 5% of doses among 1,000+ OIT patients caused any reaction, the overwhelming majority mild. "Internal data" deserves the scrutiny you would give any provider's self-reported outcomes — ask the denominator, definition and verification questions of every program, ours included. What is fair to say is that Latitude's public record is clean — no petition, no complaint clusters, affiliations with UCSF Benioff, Weill Cornell, and CHLA.

Patient reports say yes, selectively. A 36-year-old peanut-allergic patient wrote on r/peanutallergy that Latitude accepted them "although they stated they don't normally treat adults," citing a peanut component IgE threshold of 2.0 or greater, with 6–12 months to maintenance. Whether the program fee differs for adults or by allergen count is unpublished — it is one of the six written questions this page recommends asking before enrolling.

Curex's food allergy plan is $199 per month, with environmental allergy plans from $79 per month, and patients can generally save more than $10,000 over the course of treatment versus in-person programs. The trade, stated plainly: under direct supervision, clinic OIT raises reaction thresholds faster and further; at-home food SLIT uses much smaller doses under the tongue, so it is gentler, with fewer side effects, and generally a bit slower — and because fewer side effects mean fewer dropouts, more patients who start it finish it. In NIH-funded UNC studies of extended peanut SLIT, 67–70% of children reached 750–800 mg or more of peanut protein and a quarter to a third passed a full 5,000 mg challenge, with no dose requiring epinephrine (PMID 31493887; PMID 36828080). It is the first choice for families outside the coastal metros, families who move or travel, working parents and shift workers, adults, and children in sport.

Allergy Associates of La Crosse, the in-person sublingual clinic in Onalaska, Wisconsin, does: a first visit in person at a typical $750–850 ($1,000–1,400 for complex cases, allow 2–4 hours), rechecks every 3–6 months in person or virtual at about half the first-visit price, and food allergy drops at about $2.20 a day — roughly $67 a month — patient-pay, over a 3–5 year course. It treats infants through adults, including patients with a history of anaphylaxis or uncontrolled asthma, in person. It offers the same kind of treatment as the at-home route, with a clinic door in.
